Hi! After i bought a UFO burner cap it attracted 2 UFO stoves: this Hövik verk Standard and a Radius 7. It cleaned very nice, just the regular bath and a toothbrush, for some very small stubborn oxidation spots needed extra care. I changed the jet, it was burning to fet with the original one. The air screw was missing so it received a Optimus one. I didn't removed the NRV, it's working do i don't have a reason to provoke it. On the bottom has a letter "Æ" , i don't know if it has some relevance. ⚒️ ☕ As found, the Høvik is on the right one. Tomorrow it will serve the coffee☕ Cheers, Francisc
